The tiger frog belongs to Amphibia, Anuraceae, Frog family, Tiger frog genus, which is the second class of national protected animals. Its optimal growth temperature is 22-28 ℃, temperature below 4 ℃ or above 35 ℃, easy to cause death. When the temperature is lower than 12℃, it stops eating and starts hibernating, and ends hibernation when the temperature rises to 16℃ in spring. The tadpoles of the year can grow to about 150g after 6 months (May-October) of feeding. The nutrition and meat quality of tiger frogs are comparable to that of wild spiny-breasted frogs, and now the wild spiny-breasted frogs are fewer in number and more difficult to be cultured artificially, so only the tiger frogs can replace them.

1, site selection

1, site selection: should choose a quiet, easy access to water and drainage, water quality is not polluted, easy to manage the place, the area of 20 square meters is better.

2. Overwintering pool: the construction of water retention must be good, otherwise, when the water level is low in winter drought and the pool water dries up, it will cause a large number of deaths of tiger frogs due to the lack of water or frost damage. It is better to use cement pool, the depth is more than 1.5m, and the water level is kept at about 1m. In the middle of the pool, there is a resting platform which accounts for about l/4 of the total area, or another simple resting platform which floats on the surface of the water. The bottom of the pool should be put some facilities for hiding, such as straw, rubble, bamboo tube, etc., for tiger frogs to hide and hibernate.

3, spawning pool, hatching pool: the area of the best 2 square meters, so that fewer groups of pro-frogs to avoid interference with each other, the pro-frogs spawning eggs can be caught up to do hatching pool. The depth of the pool is about 1.5m, and the water level can be adjusted according to the demand, i.e. 0.2-1m. It is better to build a cement pool, if you build an earth pool, the surrounding area and the bottom should be sealed with plastic film, and the pool should be kept clean without any pollution, and at the same time, it should be kept quiet, otherwise, it will affect the spawning of the parent frogs and the hatching of the fertilized eggs.

4, tadpole pool, metamorphosis pool: the use of ladder type or slope type, the height difference of 0.2-0.3m or so, so that the pool with the tadpole metamorphosis and gradually lower the water level, fall out of part of the land for the metamorphosis of the young frog habitat.

5, young frogs, adult frogs breeding pool: there are conditions to build a concrete pool, if you use the earth pool, the pool wall should be lined with a layer of plastic film, one end of the pool is slightly higher than the other end, to facilitate the drainage of cleaning. When raising young frogs, the higher end of the pool can be used as a bait table without flooding, and the depth of the pool is about 0.5m, but there should be a 1m high fence or fence around it, and the fence should be slightly tilted to the pool to prevent the frogs from escaping.

Two, breeding methods

1, the cultivation of the parent frog: after a hibernation, to the beginning of spring that is, in early April, the temperature rises to more than 16 ℃, the parent frogs will begin to forage, at this time to feed live bait earthworms, fly maggots, etc., so that the parent frogs near the fast recovery of the physical capacity, in order to facilitate the next stage of reproduction, hatching.

2, breeding, hatching: breeding, hatching technology is the key technology of tiger frog breeding, the water temperature rises to more than 16 ℃ to make good preparations for breeding, that is, the built spawning pools, hatching pools for disinfection, and then injected into the water, and finally through the adjustment of the water level and the light to adjust the water temperature. After everything is ready, you can move the parent frogs out of the overwintering pool, and then move them to the spawning pool after taking a 5mg/l potassium permanganate bath for 5 minutes. The water level of the spawning pool should be kept at 0.2m and the water temperature should be above 20℃. Under normal circumstances, the frogs can hold on to the spawning pool for 2-3 days after entering the spawning pool. If the frogs are mature and the temperature is high, the frogs often enter the spawning pool and spawn all the eggs in 2-16 hours. The spawning pool should be observed every day after 8:00 a.m., and when the egg mass fully absorbs water and expands, it will be fished out and moved into the hatching pool. Fertilized eggs incubation optimal temperature of 25 ℃, at the same time, there should be sufficient oxygen, in the incubation of the best fertilized eggs floating in the water, if sunk to the bottom of the water, to move the fertilized eggs, so as not to stick with the bottom of the pool, resulting in the bottom of the fertilized eggs hypoxia and affect the hatching rate.

3, feeding technology: the key technology of tadpole cultivation is tadpole grading feeding. The bait is high quality and diversified. The amount of bait increased with the growth of tadpole's age, and the bait is thrown twice a day, with the artificially cultivated zooplankton and egg yolk as the main in the early stage, and the red worms as the main in the middle and late stage. Just metamorphosis of young frogs, vision and sense of smell is not yet fully adapted to the terrestrial life, at this time should be cast live bait, such as earthworms, fly maggots, etc., 5-7 days later gradually changed to feed chopped fish, mussels, snail meat, etc., and then slowly add frog material, and finally completely transitioned to the feeding of frog material. Fixed baiting, in the pool bottom to the drainage of the pool tilt, above the pool bottom area of l/4-1/5 of the land left as a baiting place or set up a fixed feed table, the amount of bait to the extent that the basic eaten within 2 hours.

Three, daily management

1, tiger frogs have the vice of eating small, should be a one-time release of the number of frogs with the same specifications, feeding 2-3 months after the individual to separate the large.

2. Tiger frogs live in caves during the daytime, so they should set up hiding places in the pool, such as planting aquatic plants or putting rubble or bamboo tubes at the bottom of the pool. Young frogs are most afraid of alarm and bright light, and they are especially sensitive to changes in the surrounding environment. Therefore, in the management of young frogs, attention should be paid to keeping the environment quiet around the pool, and shading measures should be taken in the daytime to avoid bright light and exposure to the sun.

3, timely removal of residual food, feces, replacement of pool water, to keep the water quality fresh, to reduce the occurrence of disease.

4, feeding the frog material particle size to be able to swallow a mouthful of appropriate; frog material surface smooth, absorbent softening fast, does not contain too much salt, grease and odor, feed nutrition is comprehensive, protein content of 38% or more.

5, do a good job of summer and winterization, when it is hot, we should take the water, put the water hyacinth into the pool, take the awning, spray cold water and other methods to cool down, while the winter water temperature is reduced to pay attention to heat preservation, to prevent frostbite.

Four, disease prevention and control

Red leg disease symptoms: the onset of individual mental instability, reduced mobility, abdominal distension, mouth and anus with blood mucus. At the beginning of the disease, the tip of the toe of the hind limb is red and swollen with bleeding spots, which soon spreads to the whole hind limb.

Prevention and control: (1) the sick frogs will be fished out and concentrated in a pool, soaked with gentamicin, the dosage of about 50-150mg / l, once a day for 3 days; (2) if the frogs are still able to ingest, you can add antibiotics to the feed, and at the same time, add the liver protection of multivitamin and other medicines, feeding for 3 days.

Symptoms of gas bubble disease: generally occurring in the tadpole stage, the abdomen is enlarged, and a large number of gas bubbles are gathered in the digestive tract. Prevention and treatment: control the amount of aquatic organisms in the pool, change the water diligently and keep the water quality fresh. In addition, you can add 15g/m3 of table salt to the breeding pool.Gastroenteritis Symptoms: the sick frog's food intake decreases significantly or stops eating, it is limp and weak in the pool, and it shrinks its head and arches its back when it is captured, and it can be seen that there is dendritic congestion in the appearance of the stomach and bleeding of the gastric mucous membrane, and the appearance of the intestine is reddish, and the gastrointestinal tract is empty when it is dissected.

Prevention and control: add Huanglianxin hydrochloride 4g/kg of feed or 2g/kg of flunaric acid to the feed.

EnemiesThe enemies are mainly insects in the tadpole stage, and snakes and rats in the juvenile and adult frog stage.

Prevention: (l) Keep the water inlet well, the water inlet should be filtered by sieve mesh to prevent the eggs or larvae of the enemy organisms from entering into the pool with the water. (2) The four walls of the breeding pool should be smooth to prevent the breeding of hostile organisms. You can also raise some geese, cats and other poultry and livestock outside the breeding pool to expel and eliminate snakes, rats and other pests.
